Added different loglevels

Browse Source 
I added different loglevels and (for loglevel 0 and 1) a progress bar for chapter splitting.
0 = show progress only, chapter splitting shown as progress bar
1 (default) = fewer information, chapter splitting shown as progress bar
2 = as it has been up until now
3 = debug mode
